Audi R18 rumored to be using a hybrid powertrain while testing at Sebring

“For years, Le Mans 24 Hours has served as a benchmark for sporty yet reliable cars. Audi R series had the honor of winning most of the competitions year after year, including the recent win of Audi R18 TDI this year. Car companies like Peugeot and Toyota have been looking to step up the competition by introducing their hybrid models. Peugeot is set to launch its 908 Hybrid 4, and Toyota also will have a hybrid challenger for 2012 Le Mans 24 Hours. According to the rumor, Audi’s answer to this will be a new R18 prototype that was spotted while testing at Sebring.”
